This invention relates to devices for use in the manufacture of shoes for holdingtlie uppers in lasted position, and more particularly to devices adapted for use temporarily in holding relation to the marginal portion of an upper over an insole on a last to maintain the upper in lasted position until conditions are such that it will remain in that position without the aid of extraneous fastening or holding means, as a result, for example, of the setting of cement applied to fasten the upper to the insole. The inven-- tion is herein illustrated by reference to its use in holding the toe-end portion of an upper in lasted position in the manufacture of a shoe of that kind in which the marginal portion of the upper at the toe and elsewhere is lasted over'the insole in generally parallel relation to the shoe bottom, but it is to be understood that the invention is not limited in utility to the manufacture of shoes of that particular kind nor to the lasting ofthe' toe ends of shoes.

In lasting the toe ends of shoes with cement there have been used heretofore upper-holding devices which are fastened to the shoes by tacks to maintain them in upper-holding position until the cement has set. The present invention provides a novel upper-holding device having as a partthereof means for securely fastening it to the shoe, thus dispensing with the use of tacks or like fastenings and accordingly effecting a saving of fastenings, the construction beingv also such as to facilitate and expeditethe attachment of the device to the shoe. For the purposes in view the device herein shown comprises a member adapted to be applied in holding re lation to the marginal portion of an upper over an insole on a last, and fastening means constituting apart of the device and movable relatively to the upper-holding member to mounted a head providedwith projections arranged to be forced through the V insole into the last by moving the head relatively to the memberfa spring being 'providedto; malntain' the. head. normally in a retracted position determined by "a stop. 5 The head is so formed as to serve as a handle to assist in posltion ng the device 1n proper relation to how the novel upper-holding device is ap:

plied to the toe end of'a shoe lasted in a bedlasting machine;

Fig. 2 is'a viewpartly in side'elevation and partly in section illustrating more clearly the construction of the device and'its relation to the shoe,'the toe band of the lasting machine being omitted;

Fig. 3 is a view in side elevation showing the device detached from the shoe; and

' Fig. 4 is a perspective View of the toe end of the shoe after removal of the upper-holding device therefrom. i

' The device herein shown comprises an-upper-holding member or plate 10 adaptedto be applied in holding relation to the marginal portion of the toe end of an upper extending inwardly over an insole on a last, the plate having an edge contour similar to that of the edge of the toe end of the shoe bottom and being provided along its edgewith a plurality of downwardly extending projections or teeth 12 adapted to engage the marginal portion of the upper and to penetrate the upper more or less,-forming therein small holes or'depressions indicatedat 14 in Fig. 4. For fastening the plate 10 in upper-holding position there is permanently associated with it upper-fastening means comprising a block or head 16 slidingly mounted on a. we

guiding pin 18 which is fast on the plate and projects upwardly therefrom, the head 16 having fast thereon a pair of pointed projections or pins 20 arranged to extend through holes 22 in the plate and to be forced through the insole and into the last by downward movement of the head 16 after the device has been placed upon the toe end of the shoe bottom. The head 16 is formed to serve as a handle whereby the device may be conveniently posi tioned by the operator in proper relation to the shoe, and it may be struck by ahammer to force the projections 20 into the shoe, as illus trated in Fig. 2, or. may be forced downwardly in any other convenient manner.

lVithin the head 16 there is provided a spring 24 which bears on the upper end of the pin 18 and serves normally to maintain the head in a retracted position, as illustrated in Fig. 3,

the retractive movement of the head being of a bed-lasting machine, theupper being clamped about the toe by a toe band 30 as the wipers wipe its marginal portion inwardly over the insole. The marginal portion of the upper may thus be wiped inwardly over the insole before cement is applied, and'aga-in "after the application of cement, whereupon the wipers will be somewhat retracted and the upper-holding device will be placed upon the upper with the teeth 12 nearest the endof the toe in contact with the edges of the wipers. The wipers may then be advanced and closed to force the device somewhat rearwardly over the shoe bottom andthus to draw the upper more tightly inward from the edge of the shoe bottom at the end of'the toe, the wipers also serving to locate the device in proper position widthwise of the shoe if it is not already in that position. After this the head 16 will be moved downwardly by striking it with a hammer, or in some other manner, thus forcing the projections 20 through the insole and into the last to fasten the device to the shoe. The plate 10 will thus be clamped down upon the shoe bottom through the spring 24eandpreferably also by positive engagement of the lower end of the head 16 with the plate, as illustratedin Fig. 2. The teeth 12, which may penetrate more or less through the upper materials, will then hold the toe end of the upper effectively in lasted position until the cement has set. It will be understood that the shoe will be removed from the lasting machine with the upperholding device fastened thereon. After the cement has set the device will be detached from the shoe by force applied to the head 16 or by inserting a suitable tool under the plate 10 and prying the device away from the shoe bottom.

It will be observed that the head 16 is positioned substantially midway between the opposite sides of the plate 10 on a portion of the plate which extends farther inwardly over the shoe bottom than its upper-engaging portion and is arranged in spaced relation'to the shoe bottom, and that the projections 20 are arranged to pierce the insole and'last in locations farther inwardly from the edge of the shoe bottom than the marginal portion of the upper where there is less danger of damaging the last than if the projections were arranged near the edge of the shoe bottom and where also there is no danger of disturbing the margin of the upper in removing the device from the shoe. While the drawings show two projections 20 located substantially midway between the sides of thetoe, it will be understood that the invention not limited to this particular arrangement nor, to this particular number of projections It is further to be understood that the invention is not limited to a device having teeth such. as 12 for engaging the upper.

While the invention is herein described with reference to its use on a shoe in Which the toe end of the upper is fastened to the insole by cement, it is not thus limitedin its applicability, but is useful, for example, in lasting toes including in the marginal portion of the upper box toe stifiening material which may act of itself, after hardening, to. I!

maintain the toe portion of the upper in lasted position. It will also'be evident that the device illustrated may be used, if desired, in lasting the heel ends of shoes.
